Mg/Ca, Sr/Ca, spelean fabric, and mineralogy variations in Stalagmite MAJ-1. (a) Partial image of Stalagmite MAJ-1 showing true color variations. (b) Mg/Ca ratio time series in ppm. (c) Sr/Ca ratio time series in %. (d) Converted temporal log of spelean microfabric using the code developed by Frisia38. See Fig. 2 for the explanations of the fabric codes. (e) Summary of the overall mineralogical variations based on XRD and detailed petrography, which has been color-coded to create the coloring bars in this figure and in Fig. 7
